Data Flow Diagrams/Data Flow Graph/Bubble chart

  • A DFD is a graphical shown that depicts the information flow and the transforms that are applied as the data move from input to output.
  • Level 0 DFD also known as fundamental system model or context model shows the whole software as a single bubble with input and output data indicated by incoming and outgoing arrow
